Results of a Greenhouse Study Investigating the Phytoextraction of Lead from Contaminated Soils Obtained from the Sunflower Army Ammunition Plant, Desoto, Kansas

摘要

This report describes the results of greenhouse studies conducted to determine if phytoextraction methods could be enhanced by increasing ionic lead's solubility in water. Soil acidifiers and chelating agents were used to increase lead's solubility in water. The study was conducted using lead contaminated soil from the Sunflower Army Ammunition Plant near Desoto, Kansas. These soils were shipped to the Tennessee Valley Authority's Environmental Research Facility in Muscle Shoals, Alabama, where the study was conducted. The report concludes that phytoextraction methods may be enhanced by these techniques and that the risk of leaching lead out of the soil's root zone is minimal.
